When you plug in the adapter into the laptop a LED lights up to indicate that it is connected to the mains supply and is charging.
The adapter is faulty or the connector is not making proper electrical contact. Wriggle the connector plug to see if the charge light comes on, if it does then the loose connector needs repairing.

Check the adapter with a multi-meter, the voltage reading should be a slightly higher than the voltage that is printed on the label on the adapter. If the voltage is more than 10% below the nominated voltage then replace the adapter it is faulty.

Battery is not charging


If the laptop works with the power plugged in, the battery is most likely exhausted and needs a replacement.

Acer Aspire One battery only charges to about 23%


Sadly, the only other thing you can do is buy a new battery in this instance; or continue with what you're doing.

One of the things you could do, is do not charge the computer until it dies. Batteries have a life span, and this as you may or may not know is reduced by charging, or even worse damaged more by just keeping it plugged in, charging it when it's half way charged and such on so fourth. You can increase life span by just letting it die, and then recharging it. It sounds like your battery has got to a weak point from all that charge, unplug, fall, charge. I apologize for your battery.

Asus UL50VT always shows charging


Either your battery or the power cord has an issue. Does the battery ever fully charge and make the charging light disappear or turn green? If not the battery could be bad.

Try running the computer off the battery by removing the power cord. if the battery starts losing charging strength real quick then your battery is bad. I've see bad batteries that say they are 100% charged but as soon as you remove the power cord it gets down to 5% i a matter of minutes.

Try running the computer on just the power cord. If it stays on and lets you operate without any problem then the power cord is good. A good power cord will not charge a bad battery.

If the laptop does not let you stay on long with the power cord, then either the power cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. If either of them is bad they will not charge a good battery.

Check your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

No power will not trun on


Hello

Plug in the printer power cord into electricity to charge the battery.The battery might need charging if the On light flashes green it indicates that the battery is charging.

Switch ON the printer, the battery charging icon (lightning bolt icon) flashes above the battery icon on the printer screen to indicate that the battery is charging.

If the battery is charged and the printer does not turn on with the battery power, unplug the printer power cord, if it is plugged in. Open the battery compartment and remove the battery. Wait for about 10 seconds, and then reinstall the battery.

An empty battery should fully charge in approximately four hours when the printer is not in use. If the battery still does not charge in 4 hours,you should replace it

Good luck

Hp compaq nx7400 - battery died and power cord will not turn comp


Do you have another power cord to check? Most places like bestbuy is willing to let you test a universal power cord for your type of laptop before you buy. Usually in your case, the power cord or connector has gone bad. If you test the laptop at the store and it doesnt work then its your connector but if it works. you could consider buying that power cord.

Hp compaq nx7400 - battery died and power cord will not turn comp


Some laptops will not power up with a completely discharged or faulty battery. Remove the battery from the laptop, plug in the power cord and try to boot the system. If the system boots, your battery needs to be replaced. Replace your battery as soon as you can, it's not a good idea to run the laptop for extended periods with an open battery bay.

Did the battery seem to lose it's charge rapidly prior to this, this would be an indication of a battery losing it's useful life, or a problem with the charge system.

Have you tried to take the battery out, plug the computer to a wall outlet granted you have the power adapter which is the same as the charger cord I would think. If that works I would say you need a new battery. Sometimes the plug port where it connects in the computer wears, so try and wiggle the cord if you didn't get something the first time.
